Massachusetts health officials reported another 2,650 confirmed COVID-19 cases -- the most in one day since September -- and 20 new deaths Wednesday.
The report pushed the state's number of confirmed COVID-19 cases to 823,800 since the start of the pandemic and its death toll to 18,826.
The last time the Department of Public Health reported at least 2,650 confirmed COVID cases in one day was Sept. 15, according to archival data. But that report included "a backlog of testing results" from several days prior. The previous high had been in February.
Massachusetts' COVID metrics, tracked on the Department of Public Health's interactive coronavirus dashboard, dashboard, are far lower than they were in spring, and while all of the major ones have risen from their lowest points, some have dipped in recent weeks.
